Dear Jillian:
Good question! X-rays are really a kind of electromagnetic ray which can, in effect, "shine"
through your flesh. When the ray hits the hard stuff, or bones, in your body, it makes a show which
appears on the photographic plate behind it. X-rays are remarkably valuable tools at helping
doctors "see" inside your body! Jillian, humans look so cool in x-rays. Too bad, we worms don't
have bones!
Signed,
Wendell
